To all whom it may concern: v

Be it known that 1, CHARLES E. Van Doonn, of Irondequoit, in the county of Monroe and State of New York, have 1nvented certain new and useful Improvements in l\/Iop-\/\7ringers; and I do hereby'declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of tliis specification, and to-the reference-numerals marked thereon.

My present invention relates to mop wringers and more particularly to mop wringers of the type adapted to be detachably mounted upon pails, and it has for its object to provide a simple, strong and efficient device of this nature that can be economically formedof stamped sheet material and will be light and easily assembled.

The improvements are directed more par ticularly to a novel combination of means for guiding the movable jaw of the wringer toward and from the fixed jaw through the utilization of the component parts of the wringer in a new arrangement.

To these and other ends the invention con-- sistsin certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

' v In the drawings: Figure 1 1s a front elevation of a mop wringer constructed in aucordance with and illustrating'one embodiment of my invention; Fig. 2 is a top plan view thereof, partly in section; Fig. 8 is a central vertical section; Fig. 4 is a side ele- Vation, and Fig. 5 is a section corresponding to Fig. 3, but with the movable parts in a different position.

Similar reference numerals throughout the several figures indicatethe same parts.

The main frame or body of the wringer may be stamped and formed from a single piece of sheet metal and comprises a front wall -1 constituting the fixed jaw of the wringer, and end walls 2 turned at right angles therefrom, all of said walls being provided with apertures 3, as usual, for the escape of the expressed water and the wall 1 with corrugations or irregularities, if desired. At the outer margins of the end walls 2, separate supporting plates 4 are attached. and fastened as by rivets 5, it being preferable to make these separately for reasons that will hereinafter appear. The said plates 4 have notches 6 to receivethe edge of the pail upon which the, wrin'ger is to be mounted, the extensions 7 and 8 adjacent to the notches beingadapted to bear against the inner and outer walls of the pail, re.

spectively.

he fixed aw or wall 1 isprovided near v i if its bottom with a horizontal guidingslot U preferably formed withan ad acent outwardly extendinglip 10 to give strength and an added bearing surface while the end walls 2 have substantially horizontal guides or slots 11 similarly fitted with outstanding lips 12, such slotsvll being at a relatively elevated point with reference to the slot 9.

The movable jaw of the wringer is constituted by a plate 13 approximately coex.

tensive with the wall 1 and having a parallel I movement toward and from the latter. Mo-

tion is transmitted to it by means of a trans verse shaft 14 journaled in bearing openings 15 in the supporting plates 4:. Co1nmunicatp ing slots 16 with which the openings are pro-- vided lead to the edges-of the plates 4- through which the ends of the shaft are passed when the latter is mountedbefore the plates'are attached to the end walls 2 by the fasteners 5 and that is a-reason for the separate formation of thesaid supporting plates 4:. When the latter are secured in place, the shaft, which has been thus easily assembled, is retained within its bearings and endwise thrust is prevented by suit-,

able collars 17 which may be integral with the shaft. a

The shaft is rocked by means of a handle 1 plate of the wringer and prevents the mop L head from slipping through when inserted.

This plate cooperates with the slot 9 as a guide and thus the slots 9 and 11 constitute spaced parallel guides that insure a parallel motion on thepart of movable jaw 13 relatively to the fixed jaw and prevent the At its bottom edge, the movable V former from having any tendency to bind. means for imparting motion to the movable 11', practically no additions are made to the the fixed jaw and also provided with hori-- This parallel movement is more eliicient than the pivotal movement heretofore often employed and at the same time does away with the great length of the jaw 18 that is there required in order that it may turn on a remote center and approximate parallel: ism to the fixed jaw. it will be noted, however, that in providing these guides 9 and component parts of the wringer, but on the other hand, the results are accomplished by arranging some of the parts to perform the additional functions.

The cranks 20 and links 28 constitute toggles and the two extreme positions of the movable jaw shown in Figs. 3 and 5.are themselves thought to amply explain the movement.

I claim as my invention:

1. In a mop wringer, the combination with a fixed jaw and a movable jaw and end walls connected with the fixed jaw, of guides on the fixed jaw and the end walls respectively, the last mentioned guide being locate'd above the bottom of the wringer and above the first mentioned guide, devices on .the movable jaw cooperating with said guides to give the movable jaw a parallel movement toward and from the fixed jaw and means for imparting motion to the movable jaw.

2. in a mop wringer, the combination with a fixed jaw having a horizontal slot near the bottom thereof, of a movable jaw having a parallel movement toward and from the fixed jaw, means for imparting motion to the movable jaw and a rigidly connected bottom plate on the latter cooperating with the slotin the fixed jaw as a guide.

3. In a mop wringer, the combination with a vertically disposed fixed jaw having a horizontal guide near the bottom thereof, of a movable jaw having a parallel movement toward and from the fixed jaw, means for imparting motion to the movable jaw and a rigidly connected bottom plate on the latter cooperating with the guide on the fixed jaw.

4. In a mop wringer, the combination with a fixed jaw having a horizontal slot near the bottom thereof and end walls connected with the fixed jaw and provided with horizontal guides arranged above the said slot, of a movable jaw having a parallel movement toward and from the fixed jaw,

jaw, devices on the latter cooperating with the guides on the end walls, and a rigidly connected bottom plate on the movable jaw cooperating w1th the slot in the fixed jaw as a guide. r r

5. In a mop wringer, the combination with a fixed jaw having a horizontal slot near the (35 bottom thereof and end walls connected with zontal slots located above the first mentioned slot and substantially centrally of said end walls, of a movable jaw having a parallel movement toward and from the fixed jaw, means for imparting motion to the movable jaw, devices on the latter cooperating with the slots in the end walls as guides, and a bottom plate on the movable near the bottom thereof, and end walls connected with the fixed jaw and also provided with horizontal slots, of a movable jaw having a parallel movement toward and from the fixed jaw, means for imparting motion to the movable jaw, toggle links connected to said means and having outwardly turned ends journaled in the movable jaw and also projecting into the slots in the end walls as guides and a bottom plate on the movable jaw cooperating with the slot in the fixed jaw as a guide.

7. In a mop wringer, the combination with a fixed jaw and a movable jaw and end walls connected with the fixed jaw, of sup porting plates formed separately from the end walls but fastened thereto along one edge of each to constitute extensions thereof, said supporting plates being provided wit bearing openings and with communicating slots leading from the openings to the attached edges of the plates, and means for imparting motion to the movable jaw embodying a shaft journaled in the bearing openings of the supporting plates and adapted to be inserted through the communicating slots before the supporting plates are fastened to the end walls, said end walls operating as closures for the slots to @011- fine the shaft within its bearings.
